A spokesman with Calgary-based Gemini Helicopters Inc. says it received a call from the pilot after the small Robinson R-44 went down east of Grande Cache.
Safety manager Warren Horricks says weather was poor at the time.
But staff in another aircraft managed to rescue the pilot and took him to a nearby site, where he received first aid.
He was later transported to the hospital in Grande Prairie.
Investigators are working to determine the cause of the crash.
